How to set or override User Agent value in Measurement Protocol (Google Analytics 4)?
It was easy with previous Measurement Protocol (Universal Analytics): https://developers.google.com/analytics/devguides/collection/protocol/v1/parameters?hl=en#ua
But it is not clear to me how to send User Agent to Google Analytics v4.
If you check the documentation at the top of the page Measurement Protocol (Google Analytics 4)
You will see that this protocol is still in alpha and is extremely limited there is a lot we cant do with it.
As of the time of posting this answer the answer is you cant. I suggest you wait a while as time goes on the team will begin to add new features.
